FUNGIBy Hannah and Haley Welcome to the Wonderful World of
Research Question • How does the gender of the user affect the amount of fungi on each sink? • IV: Gender of user • DV: Amount of fungi on sink (squares) • CC: • Usage ~ the same • Both sinks • Same part of sink tested (handle) • Temp. ~ same • Moisture ~ same
Hypothesis • If the user of the sink is male, then there will be more fungi on the sink handle. • Fact 1: Boys come in contact more with soil more. • Fact 2:Soil contains fungi. • Fact 3: Boys generally wash hands less often.
Procedure • Get Petri Dish and sterile cotton swab 2. Go to the girls’/boys’ restroom (depending on your gender) 3. Open swab wrapper • Give one to partner/peer (of opposite gender) • Send partner/peer to swab right handles of sinks in their restroom • Go into restroom that matches your gender • Take a swab of all sinks’ right handles • Roll the swab on the Petri Dish • Close lid • Collect close dish from partner/peer • Let sit for 2-3 days before counting
Results How Gender of Sink User Affects Amount of Fungi (sq.)
Conclusions • When the gender of the sink user is female, there are more colonies of fungi per square (2 squares). • Our hypothesis was that if the user of the sink was male, there would be more fungi on the sink handles than on the girls’ sink. Our results did not support our hypothesis, because the data showed that there were 2 more squares w/ colonies on them on the girls’ sink.
What We Learned • We learned that the girls’ bathroom sink has more fungi on it than the boys’ (thus making it highly probable girls are dirtier than boys). • We learned that no matter how likely a hypothesis is, it is often not the case, stereotypes are often incorrect, and a hypothesis can never be proven completely correct. • We would have made sure that the sinks were both in the equivalent location of the other. • We would have made sure that the sinks were thoroughly used, but not cleaned, before we tested the sinks. What We Would Have Done Differently
